BluOS is a hw/sw platform … that means that Lumïn should change its hw … it seems a pointless request, and btw… BluOS is not DSD compatible and it isn’t UPnP capable
If you like BluOS then keep a NAD/Node streamer … as you do per your signature
Sorry but I have no idea what you are talking about with those abbreviations! I don't know how or whether BluOS deals with DSD or UPnP, but as far as I'm aware, an app merely acts as a controller that introduces the server's music files to one's streamer as requested by the user and it never touches the signal iteself - surely the way most protective of the signal.
BluOS is now the control app for several brands (see under Devices here - BluOS – Premium Multi-room Music Software) and I suspect others with join the club, particularly now that it's no longer exclusively used by NAD and Bluesound. But I'm no IT expert!
